yes I did. Trophies showed up but starting a game (Like Nier, 97% trophies) results in the same black screen with error.
Only differnce between running from BD and backup is I can see the game continu behind the black screen with MM.
This CFW changed something because I also lost my PSN settings and got a black with red PSN icon I didn't have before. But before, flashing kept my PSN settings and this time it doesn't so that is maybe why it want's to sync.
Format doesn't help, going back to original settings with format doesn't help. Little stuck here. First have dinner, I will see later
And yes people: this happens when I have a clean install and just want to start an original BD. So no trophies and no PSN settings.
